Mainly motivated by the recent GW190521 mass gap event which we take as a benchmark point, we critically assess if binaries made of a primordial black hole and a black hole of astrophysical origin may form, merge in stellar clusters and reproduce the LIGO/Virgo detection rate. While two previously studied mechanisms — the direct capture and the three body induced — seem to be inefficient, we propose a new “catalysis” channel based on the idea that a subsequent chain of single-binary and binary… 
GW200105 and GW200115 are compatible with a scenario of primordial black hole binary coalescences
Two gravitational wave events, i.e. GW200105 and GW200115, were observed by the Advanced LIGO and Virgo detectors recently. In this work, we show that they can be explained by a scenario of
Compact Binary Coalescences: Astrophysical Processes and Lessons Learned
On 11 February 2016, the LIGO and Virgo scientific collaborations announced the first direct detection of gravitational waves, a signal caught by the LIGO interferometers on 14 September 2015, and
Hierarchical Merger of Primordial Black Holes in Dwarf Galaxies
We study the merger history of primordial black holes (PBHs) in a scenario where they represent the dominant dark matter component of a typical dwarf galaxies’ core. We investigate the possibility of
The Hunt for Light Primordial Black Hole Dark Matter with Ultra-High-Frequency Gravitational Waves
: Light primordial black holes may comprise a dominant fraction of the dark matter in our Universe. This paper critically assesses whether planned and future gravitational wave detectors in the

The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitational interaction is
Searching for mass-spin correlations in the population of gravitational-wave events: The GWTC-3 case study
One fundamental goal of the newly born gravitational wave astronomy is discovering the origin of the observed binary black hole mergers. Towards this end, identifying features in the growing wealth

Establishing the Nonprimordial Origin of Black Hole–Neutron Star Mergers
Primordial black holes (PBHs) from the early universe constitute attractive dark matter candidates. First detections of black hole–neutron star (BH–NS) candidate gravitational wave events by the
Stochastic Gravitational Wave Background from PBH-ABH Mergers
The measurement of gravitational waves produced by binary black-hole mergers at the Advanced LIGO has encouraged extensive studies on the stochastic gravitational wave background. Recent studies

TLDR
A fluorescence-imaging-based endoscopic capsule that automates the detection process of colorectal cancer was designed and developed in the lab and offered great possibilities for future applicability in selective and specific detection of other fluorescently labelled cancers.
Black holes merging with low mass gap objects inside globular clusters
Recently, the LIGO-Virgo collaborations have reported the coalescence of a binary involving a black hole and a low-mass gap object (LMGO) with mass in the range ∼ 2.5−5M . Such detections, challenge
Two populations of LIGO-Virgo black holes
We analyse the LIGO-Virgo data, including the recently released GWTC-2dataset, to test a hypothesis that the data contains more than one population of black holes. We perform a maximum likelihood
Minding the Gap: GW190521 as a Straddling Binary
Models for black hole (BH) formation from stellar evolution robustly predict the existence of a pair-instability supernova (PISN) mass gap in the range ∼50 to ∼120 solar masses. This theoretical
